AMD just released this month’s major update to its Catalyst software suite, Catalyst 11.7 WHQL. The new driver introduces a few major bug fixes, and provides WHQL-signed support for the recently released AMD A-Series APUs, apart from Radeon GPUs and AMD 8-series and 7-series chipset-integrated graphics.

AMD claims to have fixed all outstanding issues related to cursor-lag; a variety of system hangs noted when using HDMI or DisplayPort outputs have been fixed; a number of video playback issues, some generic and some application-specific, were resolved; the “checkerboard” pattern display corruption issue related to Eyefinity on CrossFire setups in DirectX 10 games was fixed; and flickering issues related to Portal 2 were fixed.

The driver doesn’t introduce any new features or performance improvements, but with greater stability, improved performance should naturally follow.
